Abstract: PURPOSE: To increase the output torque at the time of full load in the middle and low speed ranges by providing an aux. intake line and an aux. intake valve, divergent from the intake line, and by equipping this aux. intake line with a check valve which admits only intake flow to the cylinder.  
     CONSTITUTION: An aux. intake line 11 is provided divergent from the intake line 8 and led to aux. intake vavle 10. A check valve 12 is provided in this aux. intake line 11 and admits only the intake flow to the combustion chamber of cylinder. The opening timing of the aux. intake valve 10 is advanced in the crank angle from the opening timing of the intake valve 9. While the engine operates with full load in the middle or low speed range, the exhaust pressure is low compared with the intake pressure in the later half of the exhaust stroke, so that overlapping owing to the aux. intake valve 10 will bring about blow-bye of intake gas, and the residual exhaust gas in the combusation chamber 2 is cleaned out. Thus the intake efficiency is enhanced and the output torque of engine is increased.

Title: Sliding piston type actuator and manufacture of sliding bush
Inventor: KASHIWAGI IWAO
IPC: F01C9/00
Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To improve sealing performance by arranging a stripe shaped recessed part on the sliding surface of a swinging bush for sludably guiding a vane part in a direction perpendicular to its sliding direction, in a device formed in such a constitution that a rotor ring is eccentrically driven, the vane part is brought into sliding contact with the outer peripheral surface of the rotary ring part, and the inside of a cylinder is separated into two chambers. SOLUTION: When an eccentric rotor 2 is rotated in an arrow direction, in a swinging piston 3, the outer peripheral part of the rotor ring part 3a thereof is revolute while being brought into contact with the inner surface of a cylinder 1, a vane part 3b is slidably guided by a swinging bush 4, and thereby, a fluid sucked from a suction port 1a is discharged from a discharging port 1b after the fluid is boosted up. In this case, a stripe shaped recessed part 4a having plural belts is formed on a surface on which the vane part 3b of the swinging bush 4 is slid in a direction perpendicular to the sliding direction. It is thus possible to improve sealing performance by a labyrinth effect in the case where lubricating oil is not used. In the case where the lubricating oil is used, the lubricating oil is reserved in the recessed part 4a so as to ensure lubricating action.

Title: Screw type fluid machine
Inventor: SASAKI SHIGERU
IPC: F04C18/16
Filed: 1982-05-17
Abstract: PURPOSE:To reduce the noise of a screw type fluid machine and to improve its performance, by attaching a vibration-damping member to one end of either of two rotor shafts, and thereby damping radial vibration of two rotors. CONSTITUTION:When a compressor is set into rated operation, one end portion 2d1 of the shaft of a female rotor 2 tends to cause radial vibration almost in the state of resonance. However, since the radial vibration is damped by a vibration-damping member 13 attached to the outer circumference of a bearing 12, vibration of the end portion 2d1 of the shaft of the female rotor 2 can be damped. Thus, since the vibrational energy is absorbed by the vibration-damping member 13, almost no vibration is caused at the portion of the shaft of the female rotor 2 located on the left side of the end portion 2d1. Therefore, it is enabled to reduce the noise of a screw type fluid machine and to improve its performance.
